Got this email with links to "Linux Kit", so it grabs my attention, I clicked on it to end on a page with statements like "It's time to change …" or "It’s the time to change from windows to Linux" (note the way they wrote windowz). And it ends up as those bunch of --self censored expression-- trying to sell pirated Linux training material, so far it's cool, you can just delete this mail.
BUT WHAT DRIVES YOU REALLY NUTTS IS when a friend of your working with M$ says commenting on this stupid mail; "you linux people are spammers and above all you try to promote yourselves through selling pirated material"...

Guys, this is hillarious, the so called Bill Gates is talking about open source, and guess what he mentioned some models as "a fantastic thing" when talking about BSD and he says "we tend to favour such distribution license" (maybe because he was talking in the UC Berkley campus), but still he doesn't like GPL stating that "it should be used very narrowly" because it can't be commercial and "tax" generating as he says, for the full video checkout this link http://zdnet.com.com/1606-2-5392970.html , sadly it's in windows media or real format.
